[BIONIC MAN]

If I understand what you said, the car has done over 6000km since you took it to the drags and allegedly caused all this damage to it?!
If it broke while at the track, or soon after... Or it was a driveline related failure you would be have a harder job proving your case.
But seriously, how can it have ANY effect on the supercharger by driving down a drag strip, the charger just spins, it has no more load on it than any full throttle use on the road, and it's top speed of rotation is limited by the tune and engine rpm limiter, which has not been touched. Blower didn't know you were on a track?!?
This is bull. Don't give up on this mate ,I think there is a lot in your favour... But you are up against Ford.
As for running in, he followed the break in period as specified by FPV and I guess now Ford. He had double the kms on it when he went to the drags.
Hell, mine only had 700km on it when I went to powercruise!
